After delivering the sentence, Judge O’Neill said: “Mr Cosby you took her beautiful healthy young spirit and crushed it.”

He told Ms Constand he “heard the very clear impact” the assault had on her life.

Ahead of the sentence, the judge designated Cosby a sexually violent predator, despite the defence’s argument that Cosby’s age and blindness mean he is not a threat.

Tuesday’s classification means he will need to register with state police and notify any community he lives in of his sex offender status, as well as undergo mandatory counselling for life.

Neighbours, childcare centres and schools will have be notified of the whereabouts of the entertainer once known as America’s Dad.

The actor’s defence team had argued the state’s sex offender law was too severe given Cosby’s age and the fact that he is legally blind.

The disgraced comedian’s two-day hearing at Montgomery County Courthouse in Pennsylvania began on Monday with legal debate over the violent predator label.

Psychologist Kristen Dudley testified on Monday that Cosby showed signs of a mental disorder and was likely to re-offend.

Andrea Constand said the assault “robbed” her of her trust in others in an impact statement given to the court

In addition to the label, Cosby still faces a maximum prison term of 10 years after an agreement between prosecutors and his defence team, but there is no mandatory minimum for the convictions.

The Montgomery County District Attorney, Kevin Steele, called for five to 10 years in jail for aggravated indecent assault.

Cosby’s defence is pushing instead for house arrest.

In June 2017, Ms Constand described how Cosby, whom she viewed as a “mentor”, gave her pills that left her “frozen” and unable to stop his assault.

In Ms Constand’s impact statement, provided to reporters by the prosecution team on Tuesday, she said: “To truly understand the impact that the sexual assault has had on my life, you have to understand the person that I was before it happened.”

Ms Constand wrote that she stopped eating, sleeping and socialising in the wake of the assault. She said she had been a “young woman brimming with confidence” before Cosby took that from her.

“Bill Cosby took my beautiful, healthy young spirit and crushed it. He robbed me of my health and vitality, my open nature, and my trust in myself and others.”
